The Butterfly handheld electronic magnifier is the smallest magnifier from Zoomax equipment we could test. With the use of one button, you can do almost everything to improve your reading. At first it seems not durable, but it appeared that it's very simple to use and very useful. Thanks to it's pocket size, small weight you can use it everywhere, no matter where you are, check up receits, labels etc. It fits even the smallest bag.
